ABSTRACT:
A ring-shaped abrasive member is formed of a plurality of sheets of abrasive cloth paper laminated and bonded together. The abrasive member is formed with a plurality of cuts so as to extend inwardly from its outer edge or extend outwardly from its inner edge. On the back of the abrasive member is secured a wheel substrate together with adhesive. The abrasive member is pressed against a workpiece while rotating the abrasive member to abrade the workpiece. The powdery debris and abrasive grains trapped in the cuts will move toward the outer periphery of the abrasive member and be discharged from the outer ends of the cuts. When the topmost abrasive sheet forming the abrasive member gets worn out, the sheet thereunder will be exposed.
